Vector-type four-quark interaction and its impact on QCD phase structure
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
Effects of the vector-type four-quark interaction on QCD phase structure are investigated in the imaginary chemical potential region, by using the Polyakov-loop extended Nambu-Jona…
Phase diagram in the imaginary chemical potential region and extended Z3 symmetry
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
Phase transitions in the imaginary chemical potential region are studied by the Polyakov loop extended Nambu-Jona-Lasinio (PNJL) model that possesses the extended Z3 symmetry. The…
Polyakov loop extended NJL model with imaginary chemical potential
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
The Polyakov loop extended Nambu--Jona-Lasinio (PNJL) model with imaginary chemical potential is studied. The model possesses the extended symmetry that QCD does.…
Critical endpoint in the Polyakov-loop extended NJL model
Kouji Kashiwa, Hiroaki Kouno, Masayuki Matsuzaki +1
The critical endpoint (CEP) and the phase structure are studied in the Polyakov-loop extended Nambu--Jona-Lasinio model in which the scalar type eight-quark (σ^4) interaction and t…
